SECTION 3 <br />West Hawaii Sampling Results <br />This section presents summary composition results for the West Hawaii transfer station, <br />commercial, and self -haul substreams. The information is presented using the same formats <br />used in Section 2. More comprehensive exhibits that detail the full composition results for <br />the 58 component categories are presented in Attachment A (Exhibits A -7, A -8, and A -9). <br />Exhibits 3 -1, 3 -2, and 3 -3 show the overall composition results for waste disposed of in West <br />Hawai'i via the three substreams. Organics, paper, and construction and demolition debris <br />account for 77% and 83% of the transfer station and commercial substreams, respectively. <br />More than 90% of the self -haul substream consists of three waste categories: special waste <br />(mainly industrial sludge), construction and demolition debris, and organics. <br />Exhibits 3 -4, 3 -5, and 3 -6 show the ten largest waste components in West Hawaii for the <br />three main substreams. Cardboard is a significant component in all three substreams: 5.1% <br />for transfer stations, 9.8% for commercial, and 2.4% for self -haul. Other components that <br />appear in all three substreams include food, green waste, clean and treated lumber, and <br />R/C organic. <br />Green waste (14.4 %) is the largest component of the West Hawai'i transfer station <br />substream, and food (21.3 %) is the largest component of the West Hawaii commercial <br />substream. Food, clean and treated lumber and R/C demolition are in the top 5 of both the <br />transfer station and commercial substreams. Some components that appear in the top 10 of <br />only one of the transfer station or commercial substreams include R/C metal, ferrous metal, <br />and textiles, which are in the top 10 in the transfer station substream, and R/C paper, <br />concrete, and film plastic which are in the top 10 in the commercial substream. <br />The self -haul substream composition differs from the transfer station and commercial <br />substreams. The top three components of the self -haul substream are industrial sludge, <br />clean and treated lumber, and rocks and soil. <br />Exhibit 3 -7 shows FY 2008 tons, the number of samples taken, and composition results by <br />category for West Hawai'i transfer stations. As discussed in Section 1, the small number of <br />samples taken from individual stations means that there is considerable uncertainty <br />associated with these estimates. <br />APPX B WASTE COMPOSITION REPORT 121709DOC 3 -1 <br />
